What should I pay attention to when buying a calligraphy pen?

The pen container is shaped like a mountain peak, also called the pen mountain, because its function is to put pens and prevent ink from polluting the surrounding things, and it is also called the pen holder and pen grid. Wood, stone, porcelain, jade, etc. Can be used as a pen container, different materials, different prices. As long as it doesn't crack when choosing, it's ok to put the brush on and not roll. If it is for beginners' own use, porcelain or iron can be used in ordinary painting and calligraphy institutes, and a few dollars is very cheap. If it is a gift, the top grade is jade, ivory, crystal and other materials, but the price is not equal. Pen holder is a tool for putting pens. If you choose, it should be durable first, ornamental second and collectible last. If you really love ink, you must choose elegant tools. If you are a person who loves money, you must choose something expensive.
